v1.5.1 - Hotfix: Fixed Empty Agent Responses in Saved Conversations

🐛 Hotfix v1.5.1 - Fixed Empty Agent Responses in Saved Conversations

Critical Bugfixes

Fixed three bugs causing saved conversation files (.md and .json) to show only user queries without agent responses:

1. Streaming Event Parser (AWS Strands/Claude Agents)

• Issue: Only handled .data attribute events, missing AWS Strands .delta events
• Impact: Claude Sonnet 4.5 agents showed responses in terminal but saved empty files
• Fix: Added comprehensive fallback handling for .delta, .text, and string events
• Location: chat_loop.py:1369-1415

2. Conversation History Tracking

• Issue: History only tracked when auto_save=True, breaking manual saves
• Impact: Manual "save" command created empty files, "copy all" didn't work
• Fix: Removed conditional tracking - history always tracked regardless of settings
• Location: chat_loop.py:1595-1606

3. Harmony Processor Empty Channels

• Issue: Empty Harmony channels overwrote actual response text
• Impact: Non-Harmony agents could have responses replaced with empty strings
• Fix: Preserve original text when channels are empty
• Location: harmony_processor.py:219-226, 463-467, 502

Testing

• ✅ Added comprehensive test suite (test_conversation_saving.py, 608 lines)
• ✅ 9/9 core functionality tests passing
• ✅ 326/331 total tests passing
• ✅ All existing tests remain passing

What Now Works

✅ Universal support for all streaming formats (AWS Strands, Anthropic, etc.)
✅ Reliable conversation saving regardless of auto_save configuration
✅ Complete conversation history in both .md and .json files
✅ Manual commands ("save", "copy all") work correctly
✅ Session resume functionality works properly
